In 2013, when the state of Oklahoma erected a statue of the Ten Commandments on the grounds of the state capitol, a group calling themselves The Satanic Temple applied to erect a statue of Baphomet alongside the Judeo-Christian tablets. Since that time, The Satanic Temple has become a regular voice in national conversations about religious freedom, disestablishment, and government overreach. In addition to petitioning for Baphomet to appear alongside another monument of the Ten Commandments in Arkansas, the group has launched campaigns to include Satanic "nativity scenes" on government property in Florida, Michigan, and Indiana, offer Satanic prayers at a high school football game in Seattle, and create "After School Satan" programs in elementary schools that host Christian extracurricular programs. Since their 2012 founding, The Satanic Temple has established 19 chapters and now claims 100,000 supporters. Is this just a political group perpetuating a series of stunts? Or is it a sincere religious movement? Speak of the Devil is the first book-length study of The Satanic Temple. Joseph Laycock, a scholar of new religious movements, contends that the emergence of "political Satanism" marks a significant moment in American religious history that will have a lasting impact on how Americans frame debates about religious freedom. Though the group gained attention for its strategic deployment of outrage, it claims to have developed beyond politics into a genuine religious movement. Equal parts history and ethnography, Speak of the Devil is Laycock's attempt to take seriously The Satanic Temple's work to redefine religion, the nature of pluralism and religious tolerance, and what "religious freedom" means in America.

Though the group gained attention for its strategic deployment of outrage, it claims to have developed beyond politics into a religious movement. Equal parts history and ethnography, Speak of the Devil demonstrates why religious Satanism is significant to larger conversations about the definition of religion, religious freedom, and religious tolerance.

Laycock's Speak of the Devil is a valuable contribution to the study of modern Satanism and will be of great interest especially to those studying new religious movements, religion in America, and issues of church and state in the United States. Clearly written and well organized, the book would be ideal for graduate seminars not only for its content, but also for its expert blending of history and ethnography in its portrait of an oft-reviled minority religion.
